The aim of the development was the construction of a freely programmable handling system for use as an experimental plant for various tasks in research and development in the field of overground workings where freely programmable movement and force patterns are important. The system should be suitable for building assembly work in particular. With regard to the robot technology and the assembly operations, plans which are worked out theoretically are checked here and developed further by practical experience. The handling system constructed will be called "experimental building assembly robot".
